Local Sensors & Touch Screen
We usually count 5 senses for humans, touch, taste, smell, hearing, and sight. These are the main modes we use to take in data from the outside world as information. Similarly, a smartphone has a number of different sensors and sensing modes that enable it to take in data from the outside world. We will start exploring these today. Beyond the basic raw information, we'll discuss how more complex functions emerge when sensors are merged with computation, both in us and in smartphones.
Learning Objectives
- Enumerate sensors on modern smartphones
- Figure out how they work and explain to the rest of the class
- Learn about different modes of using some of the sensors -
Pre-Class Assignment
- Meet George Gerpheide, Utah inventor of the touch pad
- Read this short article Links to an external site. about the invention and challenges of early touch pads
- Optional: Hear a bi Links to an external site.t from George himself (you don't have to listen to the whole video, but it's fun to meet the inventor). What was the "secret sauce Download secret sauce"?
- Here's the SLC company he started: Cirque Links to an external site.
In Class Activities
-
- Break up into small groups, research a sensor and how it works, make a short (about 3 minute) power point on this sensor and how it works. Share it with the class at the end of the day.

What to submit today
- Upload your group PPTs on sensors and their use in smartphones
- Review your own privacy settings on your phone, and see if they are set in ways you are comfortable with. Describe how you decide on the tradeoffs between privacy and functionality created by sharing your information.
